Quote I didn't originally type it all in, what I did with this was to copy/paste it into Excell, shift the data around into the columns I wanted then import the Excell file into the database. So I did some typing and lots of formating. As for the 340 gr 44, I don't know what gun it was fired in but my guess would be a Super Redhawk too. Maybe a Dan Wesson, but since the SRH is so much more common that would be my guess. | |

| The penetration tests are very informative. I assume that most of the handgun loads use 'hard' bullets. What struck me most is how little increase there is in penetration between lead bullets at handgun velocities and rifle 'solids' at velocities 100-200% higher. It is almost as though beyond a certain velocity speed becomes a non-issue. For example the 500 Nitro and the 500 Linebaugh. Also, the heavy .45 and .475 loads made a very respectable showing. While the larger calibers may make larger diameter holes there really doesn't seem to be that much difference in penetration. | |

| you will gain very little in penetration with speeds over 1400fps in fact sometimes it will actually decrease. But what the tests dont show is wound channel dammage. The higher velocity loads usually have a bigger wound channel. It all depends on what you want a bullet to do. If the animal is a dangerous one I want penetration period!! if its thin skinned and not dangerous I want a combination of adequate penetation which in all cases in my book means complete penentration along with a good wound channel so I cast bullets a little softer for non dangerous game | |

| What will be interesting is if they include the Belt Mountain bronze solids next year. Those should penetrate as deeply as anything. http://www.leverguns.com/articles/beltmountain.htm | |

| John, Thanks for the post. These tests really show that some of the theorys we've been kicking around, do hold true. The velocity vs. penetration for instance, we've kicked that around quite a bit. I think it would be interesting to see wound channel results. I know we're talking wet paper and bone, not flesh and bone, but it would still be very interesting. Don | |

| Fellow Forum Members, I had a second thought on these tests. I was thinking that it would be a lot of fun and very informative for the rest of us, if we all went out and did this kind of test on our own loads. The information that we could gather as a group would be enormous, and a great benefit to us all. If we could set up a standard for the test, and all follow that standard in our testing, the results would be very uniform. What do you guys think of this? Worth a try? Don | |

| they do John we have seen penentration in wet print increase by as much as 10 inches with them over hard cast. NOTHING weve shot outpenetrates them. We shot into 3 inches of oak board followed by 40+ inches of wet news print and had them blow out the back! the bullets we did recover you could have reloaded the only efects of the shooting would be the rifling marks. Im sure Keyle will have some at the seminar for a test or two. He shot a couple last year and they did great. | |

| Don: Sounds like a wonderful idea. I did some testing like this back in the '80s with my 280. I used dry medium though (plain old bond paper) with heavy cardboard file dividers every inch or so. Not the best representation of flesh, but it gave me something to compare bullets with. Turned out the 175 Hornady SP had the best penetration, even though it was the slowest. But it didn't shoot the best in my rifle. the runner up in the penetration test, and the most accurate hunting bullet, turned out to be the 160 Speer Mag tip. Shot alot of deer with that bullet since then, none have got away! But I digress.. This is a good idea. Using a dry medium would be best for standardization, as we all do not soak the paper the same! Plus wet newprint/bond paper is messy to haul to the range for those of us who can't do this in the back yard! It would not, however, tell us much about how the bullet worked on game. Any other takers? | |

| When I've done it in the past I use phone books and soaked them in a cooler full of water, then just hauled the cooler to the gravel pit. At the time I had a pickup, so it didn't matter if a little bit spilled. You'd also have to make sure to use the same kind of paper, say newsprint without the glossy stuffers. | |

| Hey Guys, We need to settle on a testing medium that's widely available to all of us, X number of inches of newspaper would probably be the most widey available, or even sand. As far as wetting it down, we would have to set a standard for that as well, if it was a quart, or soaked for an hour, whatever you guys think would be best. Maybe as boomer said, a dry medium would be the easiest to replicate. The addition of plywood layer or layers might add to it also. Don | |

| Don: Just had another thought about wet media. Might get a little thick at my range in Jan or Feburary!  Kidding aside, that fixed amount (quart, gallon, whatever) soaking a certian amount of newsprint for a set time should be a standard most of us could duplicate. The use of tag board, plywood, etc might be a problem as the weight (grade) of the material can vary. Boomer | |

| for our standardization for fairness in testing we use news print soaked in water overnight. Winter you may need to add a little antifreeze. What we do is use 4 inches of wet print to duplicate the skin on enterance of the bullet into the animal. Followed by Appox 1 inch of oak board (we us discarded pallets) to appoximate bone and then follow with @40inches of wet print. thats enough to catch just about any bullet. We do all are shooting at 10 feet and are very careful to not shoot into the damaged parts of the test paper. this has givin up some pretty consistant results. | |

| Lloyd Smale, Thanks for giving us your formula, those materials should be available to everybody. I had wondered about freezing also, if I soak it in a tub, outside, as compared to using the bath tub. My one question is how much does all that weigh? It would be nice to have something that could be wheeled out anytime you rolled a new load to test, but this could be done periodicaly. I'm bustin' to give it a try. I have some great hardcast loads for the .44 mag. that have done great hunting. It would be nice to see how they compare in this test. Don | |

| Don: Was wondering if maybe we shouldn't start a seperate thread for this test topic. May be some folks out there intrested who haven't perused this thread yet. Boomer | |

| what we use is a large galvanized tub that was use for watering horses. we just load it in the back of a pickup and put the papers in it and add the water then we can take it to camp. By the time we get there the papers are all soaked through. Its to heavy to handle by hand when full. | |
